“Nicotine has an anti-inflammatory effect via the vagus nerve, which is useful against many diseases, and perhaps may block the cytokine storm of the H1N1 swine flu.
Nicotine stimulates the cholinergic anti-inflammatory pathway. At the end of this pathway are immune cells that produce anti-inflammatory cytokines that block inflammation. Thus, nicotine, although one of the most addictive chemicals, can have beneficial effects on inflammatory diseases, such as arthritis, asthma, cancer, inflammatory bowel diseases and perhaps, H1N1.
Tobacco Smoke Is Toxic but also Anti-Inflammatory

Paradoxically tobacco smoke contains hundreds of toxic and carcinogenic chemicals that produce inflammatory reactions and numerous degenerative diseases, but it also contains nicotine that is anti-inflammatory. Smokers assault their bodies, but moderate and obscure the inflammatory degeneration and disease, until they stop the nicotine exposure.

Nicotine Withdrawal Is Inflammatory

The anti-inflammatory benefits of nicotine reveal the inflammatory basis of many unexpected diseases. Nicotine withdrawal is severe, partly because it leads to rebound release of inflammatory cytokines, inflammation and inflammatory disease symptoms that include depression and obesity. Smoking cessation may contribute to more severe symptoms of H1N1 infections.

Nicotine Acts via the Vagus Nerve

Attempts to augment bypass surgery for weight reduction have encountered the anti-inflammatory benefits of stimulating the vagus nerve. Vagus nerve stimulation via an electrode attached to the left branch in the neck by a device implanted behind the clavicle, reduces inflammatory cytokine production and is an effective treatment for obesity. Other types of vagus stimulation are being tested for efficacy in treatment of numerous inflammatory diseases, including arthritis, allergy, asthma, Alzheimer’s, etc.”
